Abstract (en)

Disclosed are bioanodes comprising a quaternary ammonium treated Nation(R) polymer membrane and a dehydrogenase incorporated within the treated Nation(R) polymer. The dehydrogenase catalyzes the oxidation of an organic fuel and reduces an adenine dinucleotide. The ion conducting polymer membrane lies juxtaposed to a polymethylene green redox polymer membrane, which serves to electro-oxidize the reduced adenine dinucleotide. The bioanode is used in a fuel cell to produce high power densities.
